In the second part of our series we will take a look at more advanced concurrency models such as Actors, Communicating Sequential Processes, Software Transactional Memory and of course Guilds — a new concurrency model which may be implemented in Ruby 3. If you haven’t read our first post in the series, I’d definitely recommend reading it first. There I described Processes, Threads, GIL, EventMachi
September 4, 2017 The Actor Model was proposed in the '70s by Carl Hewitt as a conceptual model to deal with concurrent computation. There are a good amount of implementations out there in the wild, from complete programming languages to libraries and frameworks; the most popular ones being Erlang/Elixir and Akka. Every implementation has its own particularities, but the foundational concepts rema
Kim Woo-Bin, South Korean actor and model, has been diagnosed with a rare form of cancer, his talent agency SidusHQ confirmed in a statement on Tuesday (May 23). The Uncontrollably Fond star, who starred in breakout roles on KBS drama School 2013 and 2013's majorly popular The Heirs, is now battling nasopharyngeal cancer, a rare head and neck cancer that affects fewer than one in every 100,000 peo
Couple of months back, I was listening to Eric Evan’s pod cast on Software engineering radio where he mentioned that actor model is a great fit for modeling aggregate root in domain driven design, I was like what, wait? ain’t OO languages the only way to model concepts like aggregate, sagas, domain service, repositories or bounded Contexts in Domain driven design ? After hours of googling and days
Implementing an actor pattern that integrates with C#’s async/await keywords using less well-known regions of the .NET Task Parallel Library The actor is a widely used pattern in concurrency with strong support in languages such as Erlang and Scala. Rather than sharing data between threads and having to use locking mechanisms to synchronise access, the actor is a single entity that is responsible
Actors on a threadWriting concurrent systems is hard. A few people want to reason about low-level concurrency control primitives such as conditional locks, mutexes and semaphores; higher level mechanisms such as the actor model present lots of benefits from supervision to recovery of services/ processes. This is a sample project on using the event based actor model in python designed using gevent.
The actor model in 10 minutes 09 Jul 2015 Our CPUs are not getting any faster. What’s happening is that we now have multiple cores on them. If we want to take advantage of all this hardware we have available now, we need a way to run our code concurrently. Decades of untraceable bugs and developers’ depression have shown that threads are not the way to go. But fear not, there are great alternative
